RTGI is a "screen-space" solution. Unlike modern AAA games that use triangle-level ray tracing engines, RTGI analyzes the depth and color information of the pixels currently visible on your monitor (the depth buffer). It uses a sophisticated path-tracing algorithm to calculate how light would bounce between these pixels, adding ambient occlusion and color bleeding that wasn't there before.
ReShade RTGI is a premium shader developed by Pascal Gilcher (Marty McFly). It uses the game’s depth buffer to calculate how light should bounce off surfaces within the camera's field of view. Reshade Ray Tracing shader RTGI 0.33
Once RTGI is enabled, you will see a massive array of sliders. To achieve the perfect balance between cinematic visuals and playable framerates, tweak these core settings: 1. Ray Length and Quality
: Run the ReShade installer, select your game's .exe , and choose the correct API (usually DirectX 11 or 12). When asked to select effect packages, ensure "Addon" support is enabled if you are playing a single-player game (this helps with depth buffer detection). Add RTGI Files : Open your game's installation folder (where the .exe is). Find the reshade-shaders folder. Copy the RTGI.fx file into the Shaders subfolder. : Download the latest version from the official
The shader, specifically version 0.33 , represents a landmark in post-processing technology. Developed by Pascal Gilcher (Marty McFly), this shader bypasses the need for native hardware support or engine-level integration to bring sophisticated lighting techniques to older and non-native titles. The Mechanics of Screen-Space Ray Tracing
Version 0.33 represents a refined era of the shader, balancing sophisticated lighting fidelity with accessibility and performance optimizations. 1. Advanced Infinite Bounces (Approximated) Unlike modern AAA games that use triangle-level ray
Native ray tracing calculates light behavior by querying the entire 3D geometry of a game scene, even elements behind the player. ReShade's RTGI shader uses a clever, highly optimized alternative called .
Performance guidance
: Determines how far a ray travels to find geometry. Higher values prevent light leaking through walls but cost more performance. Set to 8–12 for optimal results. 2. Lighting and Blending
